From drawer to CNC Milling Machine

I was searching  on instructables to make a cheap CNC machine. I've found several examples and have decided to make one myself with only the parts of a office drawer (Excl. Electronics and Drive). My old home desk has one I never use so it can't be cheaper by that. With this drawer I've got enough wood to build a basic CNC. There are 4 Drawer slides voor the X and Y-axis. I'm searching for a rail to manage the Z-axis. I want to use a pitch timing belt but I don't know if my motors are strong enough for this.

An update of my progres. When the CNC will be done I will make an step to step explaination. The drawer is gone and transformed to an basic CNC table. Right now on the photo's you can only see the X axis. The Y axis is almost ready. I'm also installing the bearings on the threaded rod. The bearings I've got from my old TAX indoor Cycling trainer. When the drawer project is done I will make another CNC of the metal coming from the TAX.

The controller board for the Unipolar motors is coming from Chromationsystems.com for $45,- You can find an instructable of the controller with the following search tags (Parallel Port 3 Axis CNC Driver, Opto-Isolated, Unipolar Steppers by ChromationSystems).Or by clicking this link The power resistors are 25 Watt 10 Ohm to get 5 volt on the motors. This is working like a charm with KCAM. You can buy a full kit including stepper motors for only $ 70,- Perfect for a simple first time CNC. Here are some photo's of my status. Next time I will ad an working X-Y-and Z axis.

6 In1 Tools CNC Classic Wood Metal Lathe Milling Machine Jig-saw Driller Grinder

FAQ:
Q: What is the mini-machine? What can it do?
A: It is a delicate combination of processing units, suitable for making models or samples, technical education, product creation and invention, DIY and so on.
Q:What functions do Mini-machine have?
A:1,Jigsaw 2,grinder 3,Driller 4,wood lathe 5,metal lathe 6,Miller.
Q: What power supply does mini machine use?
A: covert from 110-240V DC power to DC14.5V.
Q: What is mini-machine made of?
A: base is made of advanced aluminum alloy, and it`s durable and not deformed, and other shell parts are made of PC plastic, some chucks are made of metal or copper.
Q: How long is the life?
A: Ten years will not be damaged under normal use.
Q: how long could the machine be used continuously?
A: In theory DC motor can be used continuously for 300 hours,but it is recommended to shutdown to save power and increase the frequency of use or life when you don`t operate it. Q: What`s the minimum hole which you can drill with the drilling?
A: Standard is 0.5mm hole. 0.4mm or 0.3mm hole is OK but you need to buy special accessories.
Q: Which parts are the consumed ones?
A: 1, belt 2, turning tool 3, drill 4, Mills 5, saw blade6, saw drive box 7,screw 8, motor fan.
Q: Is sawing machine safe?Does it injure the hand?
A: absolutely safe, even if you accidentally touch the saw blade, the hand will be safe.
Q: Why Sawing not injure the hand?
A: Because there is special-stroke design, stroke is only 3mm,it can saw off the hard objects, but the hand is soft and flexible, it will absorb the stroke, so it does not hurt the hand.
Can process integrated circuit,acrylics,plastic,gold,silver,copper,steel,aluminum

From drawer to CNC Milling Machine

I'm searching for a rail to manage the Z-axis. 

Question: I want to use a pitch timing belt but I don't know if my motors are strong enough for this. The info of my motors is: 5Volt / 1Amp / 5ohm / 6,90mH. Holding torque: 304 mN-m  /  43 oz-in    Detent torque: 12 mN-m  /  1.7 oz-in    Rotor inertia: 70g.cm2  /  0.4 oz-in2. In a few weeks it wil be transformed to a CNC machine.
